Troubleshooting System Problems
In most situations, a service ticket associates a Pathlight VX problem with a specific field replaceable unit
(FRU). Once a specific FRU has been identified, either the problem with the FRU can be corrected or the
FRU can be replaced.
To isolate Pathlight VX problems that may not be specific to a FRU, use these troubleshooting procedures:
• Troubleshooting Power Issues
• Troubleshooting Cable Connections on page 150
• Troubleshooting Temperature Errors
on page 150
• Interpreting Status LEDs
on page 151
• Troubleshooting Audible Alarms
on page 171
• Troubleshooting Pathlight VX User Interface Issues

Troubleshooting Power Issues
A power problem can cause any of these conditions:
• The Pathlight VX cannot be accessed.
• System LEDs go dark.
• A service ticket reports a power problem.
• A service ticket reports a component, software, or communication failure.
Use this procedure if a power problem is either reported or suspected.
1 Verify that all power buttons are in the on position.
2 Verify that each Pathlight VX component is correctly connected to the appropriate AC source.
3 Verify that both ends of each power cord are connected.
4 Verify that the main power breaker of the rack has not tripped and AC power is available to the Pathlight
VX.
5 Measure the AC power supplied to the rack to verify that it is within specifications. For information on
power requirements, refer to the ‘Power Requirements’ topic in the Pathlight VX Site Preparation Guide.
• If the problem is resolved, close the service ticket. Refer to Closing Service Tickets
on page 138.
• The problem is not resolved, perform these steps:
a. Modify the ticket according to the troubleshooting steps taken. Refer to Modifying Service
Tickets on page 137.
b. Contact the ADIC Technical Assistance Center. Refer to Getting More Information or Help
on
page 4.
